ATI RN Pharmacology Exam | Nurselytic

Correct Answer: C

Rationale: The correct answer is C: Assess the client's respiratory rate and oxygen saturation. Before administering Lasix to a client with heart failure, it is crucial to assess the client's respiratory rate and oxygen saturation to monitor for potential adverse effects such as respiratory distress or hypoxemia. This step ensures the client's safety and helps the nurse to detect any respiratory compromise that may occur due to the medication.

Choices A, B, and D are incorrect as they are not directly related to the immediate safety concerns associated with administering Lasix to a client with heart failure. Advising the client to avoid high-fiber foods, encouraging a potassium-rich diet, or increasing fluid intake are important considerations in heart failure management but are not specific to the immediate pre-administration assessment of Lasix.
